Abstract: A display device may include a display panel, at least one light source disposed on one side of the display panel, a circuit board to drive the light source, a light guide plate in which light emitted from the light source is incident into a surface and is emitted to another surface, and a lower frame to support the display panel and to accommodate the light source and the light guide plate. The lower frame may include a base substrate, a digitizer disposed on the base substrate, and a dummy digitizer pattern disposed on the base substrate and spaced apart from the digitizer. The circuit board may be disposed between the digitizer and the dummy digitizer pattern, and the lower frame may be bent and extend around the light source.
